- metal
- aluminum
- copper
They are installed where the roof meets other surfaces, such as:
- at joints
- intersections
. The primary role of flashing the roof waterproofing material is:
- redirect water away from vulnerable seams

Supports energy efficiency
Flashing contributes to energy efficiency in any home. The insulation of the attic can be compromised by:
- water damage
- leaks
Those can be prevented with flashing installed. It leads to increased energy, which works harder than your HVAC systems. It maintains temperature. Flashing preserves your home’s insulation by keeping your roof waterproof.
Types of flashing materials
The right flashing material depends on the following factors:
- roof design
- local weather
- budget

- lightweight
- rust-resistant
- easy to install
Copper flashing
Copper is a durable material, which is used in flashing. It is resistant to corrosion. It protects the roof and creates a visual appeal. A home looks high-end because of its classic patina look.
Galvanized steel flashing
Galvanized steel flashing offers excellent strength. It is used in asphalt shingle roofs.
PVC and rubber flashing
Synthetic flashing is flexible. It is used around pipes and vents. It is not as long lasting as metal. But, it is highly effective in preventing water leaks and irregular shapes.
Types of flashing on a roof
Each type of flashing has a specific purpose. Here are the different types of flashing to keep a home waterproof:
- Step flashing. It is installed where the roof meets the vertical wall, along with chimneys and dormers. It uses overlapping L-shaped pieces to direct water downward.
- Valley flashing. It protects the area where two roof planes meet. It ensures runoff flows smoothly.
- Drip edge flashing. It is placed along the roof edges to keep rainwater from entering under the shingles.
- Vent pipe flashing. It seals around plumbing and exhaust pipes penetrating the roof surface.
- Kickout flashing. It guides the water away from the siding at the roof to the wall intersections. It prevents staining or rot.
- Continuous flashing. It is a long strip of metal directing water down a wall or over the roof joints.
